(a) Heatmap of Spearman's correlation coefficients between relative abundance of bacterial phyla in the biomixture. The colors of the boxes indicate the value of correlation coefficients. Darkest red indicates a perfect positive correlation (r = 1), darkest blue indicates perfect negative correlation (r = -1), and fading colors indicate a gradual loss in correlation. (b) Classification of bacterial community of biomixture in term of relative abundance.
